    The grey valve on the back of the intercoller as seen in the picture. Take it of. Hold the shaft with a wrench and turn the nut until its almost at the end of the threads when u press down on the plunger it should no longer move now if it moves inward u went the wrong direction. All your doing is stopping the valve from ever being able to move again.

    So this will totally stop the valve from opening at all? not just increase the amount of pressure to open it?If so.why not just block it off?

    steve you tighten to what you feel comfortable with, all the way will block it, halfway wont and so on, it just adds spring pressure so it requires more pressure to open, yes you can just block it with a plate. this is just the cheaper way to do it.

    My boost (on the dash) dropped from all bars on (17PSI) to 13'ish by the time I got to 10 hours (from new) When I adjusted mine, I went from around 13 PSI on the dash gauge to 15+. I know it's not accurate, but even if it picked up 2 PSI more, it's not bad for a free Mod. I didn't close mine fully, just tweaked it so it "felt" twice as stiff.
